Double-insulator ice-melting grounding disconnector

Abstract

The invention discloses a double-insulator ice-melting grounding disconnector which is characterized by comprising a base plate and a disconnector body. An insulator is disposed at each of the two ends of the base plate. A equipment wire clamp is disposed at the top of each insulator. A connecting support is fixed on one of the equipment wire clamp. A clamp plate is fixed on the other equipment wire clamp. A connecting support is hinged to one end of the disconnector body through a shaft pin. The other end of the disconnector body is matched with the clamp plate. A C-shaped fixing clamp is fixed on the base plate. A clamping bolt is disposed on the C-shaped fixing clamp. The base plate is fixedly mounted on an iron tower through the C-shaped fixing clamp and the clamping bolt. The double-insulator ice-melting grounding disconnector is reasonable in design, simple in structure, good in conductivity, excellent in corrosion resistance, and convenient to operate and maintain.

Description

technical field [0001] The invention relates to a reliable grounding device for an optical fiber composite overhead ground wire (OPGW), in particular to a double insulator ice-melting grounding knife switch which can be reliably insulated after the line is covered with ice. Background technique [0002] my country is one of the countries with serious icing on transmission lines. The hazards of icing on lines are mainly manifested in tower collapse, insulator flashover, wire galloping, tripping, etc. In severe cases, it may even lead to power grid paralysis, causing great losses to national production and people's lives. [0003] However, due to the limited technical level for a long time, the OPGW optical cable cannot be completely insulated from the iron tower, so it is difficult to achieve ice melting. At present, the tower-by-tower grounding method is still adopted. After the ice is covered, the overhead ground wire will slip, causing the line to trip out of service, and...

The hazards of icing lines are mainly manifested in tower collapse, insulator flashover, wire galloping, tripping, etc. In severe cases, it may even lead to power grid paralysis, causing great losses to national production and people's lives

[0003] However, due to the limited technical level for a long time, the OPGW optical cable cannot be completely insulated from the iron tower, so it is difficult to achieve ice melting

At present, the tower-by-tower grounding method is still adopted. After the ice is covered, the overhead ground wire will slip, causing the line to trip out of service, and when the ice and snow are severe, the line will be disconnected and the tower will fall. The safe operation of the power grid will not be reliable. Assure
